In a recent study published in Physical Review Letters, the research group led by ICREA Prof. at ICFO Morgan Mitchell has detected, for the first time, entanglement among individual photon pairs in a beam of squeezed light. Quantum entanglement is always related to the microscopic world, but it also has striking macroscopic effects, such as the squeezing of light or superconductivity.

Imaging tests like mammograms or CT scans can detect tumors, but figuring out whether a growth is or isn't cancer usually requires a biopsy to study cells directly. Now results of a Johns Hopkins Univ. study suggest that MRI could one day make biopsies more effective or even replace them altogether by noninvasively detecting telltale sugar molecules shed by the outer membranes of cancerous cells.

Big data: It's a term we read and hear about often, but is hard to grasp. Computer scientists at Washington Univ. in St. Louis tackled some big data about an important protein and discovered its connection in human history as well as clues about its role in complex neurological diseases.

Researchers have made an experimental breakthrough in explaining a rare property of an exotic magnetic material, potentially opening a path to a host of new technologies. From information storage to magnetic refrigeration, many of tomorrow's most promising innovations rely on sophisticated magnetic materials, and this discovery opens the door to harnessing the physics that governs those materials.

Studies confirm that IT investments in companies improve productivity and efficiency. Univ. of Michigan professor M.S. Krishnan wondered if the same was true for government. After all, IT spending could either lead to efficiency or create bureaucratic bloat.

Chemists from Brown Univ. have found a way to make new 2-D, graphene-like semiconducting nanomaterials using an old standby of the semiconductor world: silicon. In a paper published in Nanoletters, the researchers describe methods for making nanoribbons and nanoplates from a compound called silicon telluride. The materials are pure, p-type semiconductors that could be used in a variety of electronic and optical devices.

Astronomers using observations from the NASA/ESA Hubble Space Telescope and NASA's Chandra X-ray Observatory have studied how dark matter in clusters of galaxies behaves when the clusters collide. The results, published in Science, show that dark matter interacts with itself even less than previously thought, and narrows down the options for what this mysterious substance might be.

Taking our understanding of quantum matter to new levels, scientists at Los Alamos National Laboratory are exposing high-temperature superconductors to very high magnetic fields, changing the temperature at which the materials become perfectly conducting and revealing unique properties of these substances.

Deep below the ice, far from the playful penguins and other animals that bring tourists to Antarctica, is a cold and barren world that by all indications should be completely void of life. But recently, scientists researching melting ice watched a half-foot-long (15-cm) fish swim by. Not long after that, they saw shrimp-like creatures.

In a broad new assessment of the status and prospects of solar photovoltaic technology, Massachusetts Institute of Technology researchers say that it is “one of the few renewable, low-carbon resources with both the scalability and the technological maturity to meet ever-growing global demand for electricity.”

Federal officials plan to review the safety and evidence behind alternative remedies like Zicam and Cold-Eeze, products that are protected by federal law, but not accepted by mainstream medicine. The Food and Drug Administration announced Thursday that it will hold a two-day meeting next month on regulations for homeopathic medicines, which have long occupied a place on the fringes of U.S. health care.

Researchers from Brown Univ. have completed a new analysis of an ancient Martian lake system in Jezero Crater, near the planet’s equator. The study finds that the onslaught of water that filled the crater was one of at least two separate periods of water activity in the region surrounding Jezero.

Washington State Univ. mathematicians have designed an encryption code capable of fending off the phenomenal hacking power of a quantum computer. Using high-level number theory and cryptography, the researchers reworked an infamous old cipher called the knapsack code to create an online security system better prepared for future demands.

Straw-powered cars could be a thing of the future thanks to new research from the Univ. of East Anglia. A new study pinpoints five strains of yeast capable of turning agricultural by-products, such as straw, sawdust and corncobs, into bioethanol. It is estimated that more than 400 billion litres of bioethanol could be produced each year from crop wastage.

For living organisms proteins are an essential part of their body system and are needed to thrive. In recent years, a certain class of proteins has challenged researchers’ conventional notion that proteins have a static and well-defined structure. It’s thought that mutations in these proteins, known as intrinsically disordered proteins, are associated with neurodegenerative changes, cardiovascular disorders and diseases like cancer.
